No maaan.No, jazz had it's shot. Peruvian pan-flute music will be the next big thing, then klezmer.
Polka all the way. And after that, Celtic.
Anywayz. Rock's definition has changed too much; it's waaay too broad. The Jonas Brother's Myspace considers them Rock, which is completely stupid. Pop at best, ammirite?
But, I do believe it would be nice for Rock to overcome Rap. To be honest, I always hated rap. All of my life.
